Lanthanides (Ln) find broad applications as contrast agents in medical imaging techniques such as magnetic resonance imaging (MRI). MRI is one of the most powerful, noninvasive imaging procedures, which is able to create images of tissues, organs and diseases in vivo. Every year, about six million patients undergo MRI studies of which 30% are performed using Gd-based contrast agents (CAs), whic...

Human beings are unavoidably exposed to ambient electromagnetic fields (EMFs) generated by every instrument that uses electricity. Electromagnetic fields are made by the combination of an electric field and a magnetic field and is propagated in a wave like manner. Thus sometimes called electromagnetic waves and or electromagnetic radiation. Under such condition the indoor and outdoor environmen...

introduction: the effects of electromagnetic fields on biological organisms have been a controversial and also interesting debate over the past few decades, despite the wide range of investigations, many aspects of extremely low frequency electromagnetic fields (elf/emfs) effects including mechanism of their interaction with live organisms and also their possible biological applications still r...

Recent neurophysiological studies indicate that exposure to electromagnetic fields (EMFs) generated by mobile phone radiation can exert effects on brain activity. One technical solution to reduce effects of EMFs in mobile phone use is provided in mobile phone chips that are applied to mobile phones or attached to their surfaces. To date, there are no systematical studies on the effects of mobil...

The expanding marine renewable energy industry will increase the prevalence of electromagnetic fields (EMFs) from power cables in coastal waters. Assessments environmental impacts are required within licensing/permitting processes and increased questions concerning EMF emissions potential cumulative impacts. It is presumed that protecting a cable by burial, may also mitigate on species. Focussi...

Journal: :Journal of Epidemiology and Community Health 2021

New fifth generation (5G) telecommunications systems, now being rolled out globally, have become the subject of a fierce controversy. Some health protection agencies and their scientific advisory committees concluded that there is no conclusive evidence harm. Several recent reviews by independent scientists, however, suggest significant uncertainty on this question, with rapidly emerging potent...

Although there is no certain known mechanism of how the electromagnetic fields (EMFs) at power frequency (50/60 Hz) can affect human health, it has been epidemiologically shown that they have many hazards on human health. Also the power frequency fields may interfere with the nearby electrical and electronic equipment. In response to the precautionary principle, it might be needed in some situa...
